Japan's toilets are genuinely extraordinary — heated seats, bidets, automatic lids, ambient sounds, and controls that vary from hotel to hotel. First-time visitors often find the panel intimidating. This guide demystifies every function.
The Standard Control Panel
Most Japanese high-tech toilets (washlets, manufactured primarily by TOTO and Panasonic) share a core set of functions regardless of model:
- おしり (Oshiri / Rear wash): Posterior bidet wash — adjustable pressure and position
- ビデ (Bide / Feminine wash): Frontal wash — softer pressure, more forward nozzle
- 乾燥 (Kanso / Dry): Warm air dryer — slow but effective
- 止 (Tome / Stop): Stops any active function — the most important button to locate first
- 音楽/音 (Oto / Sound): Plays a water-flushing sound to mask bathroom noise — a uniquely Japanese privacy feature
- 蓋 (Futa / Lid): Opens or closes the seat lid automatically
- 温度 (Ondo / Temperature): Adjusts seat warmth and wash water temperature
- 強/弱 (Pressure): Water pressure control for the wash function
How to Use the Bidet Function
Sit on the toilet normally. The nozzle extends automatically when you press おしり or ビデ — it doesn't require positioning on your part. Water temperature and pressure are pre-set but adjustable. Press 止 (stop) when finished. The nozzle retracts and self-cleans. The seat's built-in warm air dryer (乾燥) is gentle and takes 1–2 minutes; most hotels also provide toilet paper as a backup. Paper is always provided — Japanese plumbing accepts toilet paper (unlike many Asian countries).
Finding Good Toilets
Japan has an extraordinary density of clean public toilets — in train stations (always), department stores, convenience stores (7-Eleven and Lawson require purchase; FamilyMart is usually open), temples and shrines, and parks. The Tokyo Toilet Project commissioned 17 designer public toilets across Shibuya ward, each by a different architect — including glass-walled transparent toilets that turn opaque when locked. These are genuinely worth seeking out as design objects.
Squat Toilets
Western-style toilets are dominant in all tourist areas, hotels, and modern buildings. Squat toilets (washiki) still appear in older stations, rural rest stops, and some traditional establishments. If you encounter one: face the hood end (the raised curved end, away from the door), squat low, and use the control on the wall or handle to flush. They work well once you understand the orientation.
Etiquette
Always use the toilet-specific slippers provided in ryokan bathrooms (never wear bathroom slippers back into the main room — a common tourist mistake). Flush at the end of your visit — the 流す (nagasu / flush) button is typically large and separate from the bidet panel. Leave the seat in the position you found it (usually down, lid closed).
